Kim Kardashian West and Kanye West Announce Name of Third Child

Kim Kardashian and Kanye West’s have confirmed the name of their third child: Chicago West.

The reality television star announced the news on her app, publishing a post simply titled "Chicago West," along with the baby’s birthday, birth time, and birth weight. It's not the only news they've announced via mobile: the original news of the baby’s arrival, too, was first published on Kim's app.

Chicago West is the youngest of three, joining 4-year-old sister North and 2-year-old brother Saint. She'll soon get to greet a couple of cousins as well, since Kim's sisters are also pregnant. Khloe Kardashian confirmed that she's expecting a baby with boyfriend Tristan Thompson with a bump-bearing photo posted on Instagram in late December. Kylie Jenner is also reportedly pregnant, expecting her first child with boyfriend Travis Scott.

Kim chose to have a baby via surrogate after suffering from a condition called placenta accreta, which she's been candid about on Keeping Up With the Kardashians. And while the business woman and social media superstar is in charge of an ever-expanding empire, she has written that "being a mom is the most important job I have."
